Description

Closing device for a packing bag and packing with a closing device.

The invention relates to a device of closure for a packing bag comprising an opening of extraction in which the closing device can be mounted forming an extraction channel, with an inner tightening part which can be introduced at least partially in the bag of packing, passing through the extraction opening, an outer part of tightening that can be connected to the inside of squeeze, squeezing a marginal area, surrounding the opening of removal, from the packing bag, and a cover part that it can adopt a closing position by sealing the extraction and a release position releasing the channel from extraction.

Additionally, the invention relates to a packing with a flexible packing bag to receive a plurality of wet wipes, being configured in a side surface of the packing bag an opening of extraction in which a closing device can be mounted forming a closable extraction channel.

Particularly in relation to products cosmetics, for example cosmetic wet wipes, impregnated of a liquid and / or a medium to be applied, for example a lotion, It is known to use a packing bag as outer packaging flexible, formed of a plastic sheet. Wipes impregnated are closed in the packing bag so tight against air and liquids. After the user has open the packing bag, there is a risk that the wipes impregnated, arranged inside the packing bag, with the over time they dry out or get dirty, for example covering themselves with dust, and can no longer be used, which should be avoided.

For this reason it is known to provide an opening extraction on a side surface of the packing bag and apply in the packing bag, near the extraction opening, an adhesive flap that can be placed over the opening of extraction in an adhesive and therefore airtight manner, and, in If necessary, it can be separated from it. The disadvantage of this configuration, however, is that the adhesion effect decreases over time and therefore no longer ensures the tightness of the extraction opening. This problem occurs especially if the marginal area of the extraction opening has been soiled after the removal of some wet wipes by the means by which wet wipes are impregnated, or if dust and dirt settle on the adhesive layer. These means, for example a cleaning lotion, decrease essentially the adhesion effect of the adhesive flap, so that the packaging bag loses its tightness soon after use time.

To solve this problem, in the DE-U 9317973 has proposed a device for closure for a packing bag that can be arranged in the extraction opening of the packing bag and can be closed or open by a user as many times as you want, without reducing the sealing effect.

The device consists of an inner part of tighten in the form of an annular plate comprising an opening central with a cylindrical tube that protrudes axially.

The annular plate is introduced by the user by the extraction opening in the packing bag and it is positioned in such a way that the cylindrical tube crosses the extraction opening and protruding from it on the outer side of the packing bag. On the protruding tube, a ring External tightening can be placed on the outer side of the packing bag so that the marginal area of the bag packing around the extraction opening is tight fixedly, hermetically, between the inner annular plate and the outer clamping ring. A cover is connected through an integral blade hinge with the clamping ring and can be placed on the clamping ring in such a way that the opening of packing bag removal is tightly closed. Opening the cover, a user will have access to the wipes wet found inside the bag packaging.

When all the wet wipes in the bag Packaging are worn out, the closing device can separate from the packing bag and can be reused in Another packing bag. For this purpose, the user separates the connection between the inner ring plate and the outer ring of tighten and then you can remove the tightening ring with the cover attached by molding. However, in this case there is risk of the inner annular plate falling into the bag of packaging and get dirty with the remains of the lotion or liquid with which the wet wipes were impregnated. For avoid it, the user will have to try to keep at the same time the inner ring plate and remove the outer clamping ring. This is relatively difficult and complicated and undermines essential the comfort of use of the closing device. Additionally there is a risk that the annular plate and / or the tightening ring, when the user has separated the device of closing an empty closing bag, temporarily storing it. The loss of one of the two pieces leads to the impossibility of Use the entire closing device.

The object of the invention is to provide a closing device of the indicated nature that can be operated easily, quickly and conveniently apply to the bag packing and separate from it. Additionally, it must be provided easy handling packaging comprising a device corresponding closure.

As regards the closing device, This object is solved by the characteristics of the claim 1. In this case it is provided that the inner part of tighten, the outer tightening part and the cover part are connected to each other through nerves and performed under the One-piece form molded by plastic injection. This one-piece configuration of the entire device of closure has the advantage that none of the pieces can be lost, and also when assembling or separating the device from closure ensures that particularly the inside tightening part cannot fall into the packing bag because it is connected fixedly with the outer part of tightening.

In a possible embodiment of the invention is provided that the entire closing device, that is, the part inner tightening, the outer tightening part, the part of cover and nerves are composed of a uniform material synthetic. Alternatively, however, it can also be provided that the closing device consists of at least two Different synthetic materials. In a possible embodiment it is provided that the inner part of tightening, the outer part of tighten and cover part consists of a first material synthetic and nerves that must be configured so flexible and so that they can be deformed so relatively easy, mainly due to opening movements and closing the cover, consist of a second synthetic material, different from the first.

Figure 1 shows a perspective view of a packing 1 in the form of a flexible packing bag 2 which It consists of a tubular sheet of plastic material and is closed from usual way through heat sealed seams 3 formed in the extremities. On a lateral surface 2a of the packing bag 2 an extraction opening 4 is configured (see figure 8) in which a closing device is mounted 10 tightly. In figures 2 to 7, the device closure 10 is represented in details and is described in the details below.

The closing device 10 comprises a part tightening interior 12 presenting an oval plate section and of ring shape 18 with a first central opening 20. On the edge inside, surrounding the first central opening 20, of the section of annular plate 18 is joined by molding a tube 21 that extends essentially in the vertical direction with respect to the section of annular plate 18 and protrudes therefrom, as can be seen especially in figure 5. The tube 21 also has a shape oval and comprises in its two longitudinal surfaces respectively a blocking projection 26. Each blocking projection 26 is configured and molded on the outer side of the tube 21 a a distance from the plate section 18. Such as Figures 4 and 5 show, the locking protrusions 26 are extend respectively in the central area of the edges lengths of the oval tube 21, by a partial section of the longitudinal edges

The annular plate section 18 comprises in a narrow surface an insertion boss 19 joined by molding and protruding outward, presenting a conical shape that It narrows outwards.

On the narrow surface, opposite the ledge of introduction 19, the inner tightening part 12 is connected through a first nerve 17 in one piece with a part external clamping 11. The external clamping part 11 comprises also an annular plate section 14 defining a second central opening 15. In the inner edge, surrounding the second central opening 15, of the ring plate section 14 is molded a circumferential collar 16 protruding from the plate section annular 14. The inner tightening part 12 can be rotated with with respect to the outer part of tightening 11 by the first rib 17 such that the tube 21 of the inner tightening part 12 is insert with narrow adjustment in the second central opening 15 of the outer part of tightening 11, until the locking projections 26 have passed the collar 16 of the outer tightening part 11, overlapping with it, as shown in figure 7. In this state, the ring plate section 18 of the inner part of tighten 12 and the annular plate section 14 of the outside of tighten 11 are superimposed under previous tension, if any interposing the wall of the packing bag, whereby the closure device 10 is mounted tightly in the bag of Packing 2, as will be described later in detail.

The first nerve 17 that connects the part inside tightening 12 with the outer tightening part 11 is formed as a flexible and low pressure tape, molded with a of its limbs in the inner part of tightening and with the other of its extremities 17a (see figure 5) on the surface outside of the tube 21, at a distance from the section of annular plate 18. The other extremity of the first nerve 17 is molded on the outer edge of the annular plate section 14 of the inner tightening part 11, on the narrow surface of the same. In this case, on the surface of the annular plate section 14 of the outer part of tightening 11 which, in the state in which it is interlocked with the inner tightening part 12, it is oriented towards the ring plate section 18 of the inner clamp plate 12, a recess 25 is configured (see figure 4), in which the first nerve 17 is housed at least almost entirely, when the two clamping parts 11 and 12 are locked one with the other. In this way, in the locked state of the parts of tighten 11 and 12 the annular plate sections 14 and 15 can be superimposed on each other with its entire surface.

On a longitudinal side of the plate section annular 14 of the outer part of clamping 11 is joined by molding a second nerve 22 that is also shaped as a thin tape and flexible and that is connected at its tip away from the outer part of clamping 11 with a cover part 13. The part of cover 13 comprises a cover plate 23 on which a retaining projection 24 is molded, configured as a wall circumferential. The outer dimensions of the projection of retention are configured so that it can be introduced with tight fit or under slight deformation elastic in the first central opening 20 of the inner part of press 12 and there it will be held securely by friction. The cover plate 23 is also oval shaped and sticks out the entire circumference outwards, beyond of the retention boss 24, so that it rests on the upper surface of the tube 21 of the inner tightening part 12 so that it covers it, when the retention boss 24 is introduced in the first central opening 20 of the inner part of tightening 12.

The assembly of the closure device 10 in the packing bag through the Figures 8 to 10.

As Figure 8 shows, in a first time the inner tightening part 12 is introduced into the opening  extraction 4 of packing bag 2 (arrow A), which is provided by the conical introduction boss 19. In the state inserted from the inside of clamping 12, on the lower side of the marginal zone 2b, surrounding the extraction opening 4, of the packing bag 2, the inner tightening part 12 is adjacent to the wall thereof, and the tube 21 of the inner tightening part 12, whose outer dimensions correspond essentially to the internal dimensions of the extraction opening 4, crosses the extraction opening 4 and protrudes outward as is represented in figure 9.

Then the outer part of tightening 11 it is rotated in such a way with respect to the inner tightening part 12 (arrow S), which is placed with the second central opening 15 with tight fit on the tube 21 of the inner tightening part 12, until the retention projections 26 overlap the collar 16 of the outer part of tightening 11. In this state, the area marginal 2b of packing bag 2 is tightly tightened tight between the two clamping parts 11 and 12. This state is represented in figure 10. In this case, the first opening center 20 of the inner tightening part 12 and the second opening center 15 of the outer clamping part 11 are located in aligned arrangement and form an extraction channel E, through the which a user can remove a wet wipe T that is inside the packing bag 12.

To close the extraction channel E, the user turn the cover part 13 around the second rib 22 with with respect to the two clamping parts 11 and 12 fixedly locked the with each other, until retention boss 24 is squeezed into the extraction channel E and the cover plate 23 is placed on the extraction channel E, on its upper side. This state is represented in the Figures 6 and 7. For the extraction of a wet wipe T, the user can remove the cover part 13 of the extraction channel E and in this way you get access to the wet wipes T.
